Picture an extra living space flooded with natural light. Our 3-4 season rooms are perfect for a variety of uses, from a dining area to a home office or a playroom for the kids. We design these spaces to be as functional as they are beautiful, creating versatile rooms that adapt to your family’s needs.
Unlike traditional sunrooms, a four-season room is designed to be enjoyed year-round. Because it is fully insulated and climate-controlled, you can stay cool in the summer and warm in the winter. This makes it a true extension of your home’s living area, offering a comfortable retreat no matter the weather outside.
Our team has years of experience in high-quality addition work. We ensure that your new room looks and feels like it was always part of your home. We pay close attention to every detail, from matching the exterior materials to creating a seamless transition from your existing home into the new space.
our Process
Every project follows the same five steps, so you always know what comes next and what it costs.
1
We meet within 48 hours of your form to talk through how you’ll use the new space and what you want it to do for your home.
2
We turn your goals into a design and 3D renderings, so you can picture the finished room before any work starts on your home.
3
Our quote itemizes permits, engineering, materials, and labor, and we handle every filing with town building inspectors and HOAs.
4
Our crew frames to engineered load requirements and runs a multi-point checklist at every stage, catching small issues early.
5
We walk the finished room with you, go through every item on the list, and hand over your warranty packet before we wrap up.
A new room becomes part of the house for decades, so we build it that way. We set the schedule up front and tell you early when it shifts. We won’t skip a step to hit a date, and our framing gets the same care as the finish work.
Allan Trant Exteriors, founded in 2014, is built on a legacy of craftsmanship spanning three generations. Allan Trant, a third-generation carpenter, grew up immersed in the art of construction. He learned the values of precision, hard work, and customer-first service from a young age. Today, his team specializes in creating high-quality decks and outdoor living spaces, delivering projects that reflect integrity and lasting value.
More than just a builder, Allan Trant Exteriors prioritizes personalized service and honest craftsmanship. From using premium materials to ensuring clear communication and timely project completion, we are committed to turning homeowners’ visions into reality. With a foundation of integrity and community commitment, our team creates spaces that homeowners can cherish for years to come.
A new room is a big investment, and we treat its protection that way. Every addition, from a finished basement to a four-season room, carries a one-year workmanship warranty on our crew’s work. The manufacturers’ warranties on your materials cover the products themselves. You’ll get a warranty packet with every detail spelled out before we wrap up. Knowing exactly what’s covered, and for how long, makes the years after move-in a lot easier.

Traditional sunrooms aren’t meant for year-round use. A four-season room is fully insulated with heating and cooling, so it stays comfortable in July and in January.
Yes, that’s the whole point. Because the room is climate-controlled, a snowy February afternoon feels as comfortable as a warm June evening.
It works well as a dining area, a home office, a playroom for the kids, or a quiet spot to read. We shape the layout around how your household actually lives.
That’s the goal. We match the exterior materials and build a smooth transition from your existing home into the new space, so the addition feels like part of the house from day one.
Based in Nottingham, we manage the entire permitting process, including working with town building inspectors and HOAs. You won’t have to chase paperwork, and the project keeps moving.
